The financial accelerator effect: concept and challenges

This review concentrates on the role of information asymmetry in financial markets in the amplification and propagation of short-run output fluctuations. We find that the financial accelerator effect, as it is known, provides a consistent, first principle based, theoretical framework for the analysis of the relationship between financial markets and short-run output fluctuations. It also provides a plausible explanation of the proximate causes of the recent crisis, and first principle-based theoretical background for the credit policy measures taken during this crisis by many central banks and fiscal authorities. Despite the theoretical plausibility, the empirical evidence about the economic importance of the financial accelerator effect is still relatively weak. We also suggest two new aspects to expand existing concept of the financial accelerator effect, which call for further research.economic forecasting, density forecasting, fan chart, stochastic simulations, uncertainty, Croatia

Indexed debt contracts and the financial accelerator

This paper addresses the positive and normative implications of indexing risky debt to observable aggregate conditions. These issues are pursued within the context of the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The principal conclusions are that the optimal degree of indexation is significant, and that the business cycle properties of the model are altered under this level of indexation.Indexation (Economics) ; Financial markets

De-leveraging and the financial accelerator: how Wall Street can shock main street

The severity of the recent economic downturn raises questions about the role of financial markets in modern market economies. Why did rising defaults in a relatively small portion of the U.S. housing market cause a financial crisis? Why do financial crises have outsized adverse effects on the rest of the economy? As a general rule, a decline in economic activity in the nonfinancial sector, such as occurs during a typical recession, induces greater restraint on the part of the financial sector and that restraint - manifested usually in a pullback of credit and funding - in turn causes further setbacks to the nonfinancial sector. In the academic literature, this feedback effect is called the financial accelerator. In "De-Leveraging and the Financial Accelerator: How Wall Street Can Shock Main Street," Satyajit Chatterjee looks at what underlay the financial shock that emanated from Wall Street in the fall of 2007. Then he focuses on the channels through which the financial accelerator works and how the accelerator can turn a financial market disruption into a deep recession.Financial crises ; Recessions

Monetary Policy in an Estimated DSGE Model with a Financial Accelerator

This paper estimates a sticky-price DSGE model with a financial accelerator to assess the importance of financial frictions in the amplification and propagation of the effects of transitory shocks. Structural parameters of two models, one with and one without a financial accelerator, are estimated using a maximum-likelihood procedure and post-war US data. The estimation and simulation results provide some quantitative evidence in favour of the financial accelerator model. The financial accelerator appears to play an important role in investment fluctuations, but its importance for output depends on the nature of the initial shockMonetary policy, Financial accelerator, DSGE estimation

An Estimated Small Open Economy Model of the Financial Accelerator

This paper develops a small open economy model in which entrepreneurs partially finance investment using foreign currency-denominated debt subject to an external finance premium. We use Bayesian estimation techniques to evaluate the importance of balance sheet-related credit market frictions for emerging market countries by incorporating the financial accelerator mechanism. We obtain a sizable value for the external finance premium, which is tightly estimated away from zero. Our results support the inclusion of the financial accelerator in an otherwise standard model that-acting through balance sheets-magnifies the impact of shocks, thereby increasing real and financial volatility.

The External Finance Premium and the Macroeconomy: US post-WWII Evidence

This paper embeds the financial accelerator into a medium-scale DSGE model and estimates it using Bayesian methods. Incorporation of financial frictions enhances the model's description of the main macroeconomic aggregates. The financial accelerator accounts for approximately ten percent of monetary policy transmission. The model-consistent premium for external finance compares well to observable proxies of the premium, such as the high-yield spread. Fluctuations in the external finance premium are primarily driven by investment supply and monetary policy shocks. In terms of recession prediction, false signals of the premium can be given an economic interpretationfinancial accelerator, external finance premium, DSGE model, Bayesian estimation

External Constraints on Monetary Policy and the Financial Accelerator

We develop a small open economy macroeconomic model where financial conditions influence aggregate behavior. We use this model to explore the connection between the exchange rate regime and financial distress. We show that fixed exchange rates exacerbate financial crises by tieing the hands of the monetary authorities. We then investigate the quantitative significance by first calibrating the model to Korean data and then showing that it does a reasonably good job of matching the Korean experience during its recent financial crisis. In particular, the model accounts well for the sharp increase in lending rates and the large drop in output, investment and productivity during the 1997-1998 episode. We then perform some counterfactual exercises to illustrate the quantitative significance of fixed versus floating rates both for macroeconomic performance and for welfare. Overall, these exercises imply that welfare losses following a financial crisis are significantly larger under fixed exchange rates relative to flexible exchange rates.

Confidence and the Financial Accelerator

We introduce financial frictions in the spirit of Bernanke, Gertler, and Gilchrist (1999) into a standard RBC model and use the heterogeneous-prior framework of Angeletos, Collard, and Dellas (2018) to accommodate confidence-driven business cycle fluctuations. We show that financial frictions strongly amplify the response to confidence shocks—more strongly than the response to fundamental shocks. Furthermore, we show that in the presence of financial frictions, prolonged episodes of unfounded optimism cause boom-bust cycles in investment and to a lesser extent in output. In particular, the financial state of the economy deteriorates severely after the initial boom, which leaves the economy more vulnerable to adverse shocks
